Vietstock Weekly (Sept 29 – Oct 3, 2025): Liquidity Lacks Momentum – Can the Market Break Through?
The VN-Index edged higher following a volatile week of trading. While the MACD indicator has maintained a buy signal since May 2025, its divergence from the Signal Line is narrowing. Meanwhile, the Stochastic Oscillator continues to weaken after a sell signal in overbought territory, suggesting short-term volatility remains a risk. Additionally, declining trading volumes in recent weeks indicate a lack of momentum, making a clear breakout unlikely unless liquidity improves soon.
